Debian has entered "Transition freeze".
Transition freeze ... means no new library transitions or package transitions that involve a large
number of packages.
Full freeze: Feb 5 2017.
As always, Debian 9 "Stretch" will be released "when it's ready".

For that matter, I am running Debian Stretch armhf [debian.org]--running a LAMP stack and the LXDE desktop--on an A20 Arm-processor based Olimex Lime2 single board computer [olimex.com], and have been for a while.
I upgraded the little Arm machine just as described above, by updating /etc/apt/sources.list and apt-get update && apt-get dist-upgrade. Stretch is out there and working, even without being blessed with the "released as stable" nomenclature.
(Unrelated: By the way, if you've heard that Arm processors can be slow compared to nice fast traditional PCs or servers, you heard right.)
